ELECTRICAL WORK
The electrical work should be performed by a specialist qualified for the work.
◆ Use the three phase power supply, and be sure to install the sub power distributing board for
exclusive use with the unit(separately purchased by the user).
❈ Avoid octopus-type wiring as it can cause a drop in voltage, thus resulting in poor performance
of the automatic control circuit.
◆ Be sure to install circuit breaker (separately purchased by the user).
◆ Be sure to connect the grounding wire.
◆ When connecting the wiring harness between the indoor and outdoor unit, align the outdoor side and the
indoor side with the terminal board No.
◆ Connect the connection wire (1, 2, 3) and power cable (L1, L2) to terminals through the conduit hole
as shown in the diagram.
❈ When the wiring harnesses of the indoor and outdoor unit are not properly connected, it may cause trouble.
Be careful not to allow the indoor and outdoor wirings and power lines to get in contact with the service valve
of the refrigerant system or to the pipe without an insulator.
